Tuna melt

This is one of my favorite lunches when it's cold out.  Nearly too simple for a recipe.

 
Ingredients:
1 can tuna
a couple of tablespoons mayo, to taste
1 T pickle relish, to taste
2 slices cheese, any sort (pictured above is cheddar and swiss)
2 thick slices of bread

Directions:  
Preheat oven to 400 degrees.  Mix tuna, mayonnaise, and pickle relish, to taste.  Spoon tuna salad onto bread; put cheese on top.  Bake in 400 degree oven until cheese is bubbly and just starting to brown, about 10-15 minutes; bread will be toasted by this point.
